Coenzyme Q-10 (as ubiquinone) performs several important health supporting roles in the body. Ubiquinol (the reduced form of CoQ-10) provides advanced antioxidant support. By supplementing with Ubiquinol, you are providing your body with a form of CoQ-10 that is in a ready-to-use state to fight free radicals. Free radicals can cause oxidative stress which may damage cells. Solgar Ubiquinol 100 mg is offered in oil-based softgels to ensure optimal absorption and assimilation.
